DRAT-TRIM(1)

✨ DRAT-TRIM(1) — the manual, but make it make sense ✨

okay bestie, sit down, hydrate, and let me tell you about drat-trim — the DRAT-trim Satisfiability Proof Checker 💅 this is a User Commands page, so you already know it's gonna be giving "I live in your terminal and I'm iconic".

🎀 NAME 🎀

drat-trim — DRAT-trim Satisfiability Proof Checker. no cap, that's literally the whole name. that's the brand. that's the vibe. ✨

---

🦋 DESCRIPTION 🦋

so here's the tea, the synopsis, the whole main-character entrance:

drat-trim [INPUT] [<PROOF>] [<option> ...]

and <option> is one of the following, and yes we're going through all of them, no skipping, no skimming, this is a completionist household 🫶

• -h — prints this command line option summary. it's the "help me bestie" button 💖
• -c CORE — prints the unsatisfiable core to the file CORE, in DIMACS format. the receipts, but for unsatisfiability ✨
• -a ACTIVE — prints the active clauses to the file ACTIVE, in DIMACS format.
• -l LEMMAS — prints the core lemmas to the file LEMMAS, in DRAT format.
• -L LEMMAS — prints the core lemmas to the file LEMMAS, in LRAT format. yes it's a different letter than -l, and yes that matters, look at them again 🔍 (one is lowercase, one is uppercase, do not mix them up, I am begging 🙈)
• -r TRACE — resolution graph in the TRACE file, in TRACECHECK format. it's giving family tree but for logic 🌳
• -t <lim> — time limit in seconds. default is 40000. that's a lot of seconds. that's a whole situation of seconds ⏳
• -u — default unit propatation, i.e., no core-first. (that's spelled exactly like that in the original, and I'm keeping it, we don't edit the ancestors 💀)
• -f — forward mode for UNSAT.
• -v — more verbose output. it will simply talk more. relatable, honestly 🗣️
• -b — show progress bar. visual feedback, we love to see it ✨
• -O — optimize proof till fixpoint by repeating verification. it keeps going until it can't go anymore. queen behavior 👑
• -C — compress core lemmas (emit binary proof). tiny proof, big energy 🌸
• -D — delete proof file after parsing. bestie it deletes it. after parsing. it's gone. be so serious about this one 😭
• -I — force ASCII proof parse mode.
• -i — force binary proof parse mode. (-I and -i are NOT the same thing, casing is load-bearing, iykyk)
• -w — suppress warning messages. the warnings just… stop 🦋
• -W — exit after first warning. one warning and it's out the door, no second chances 💅
• -p — run in plain mode, i.e., ignore deletion information.
• -R — turn off reduce mode.
• -S — run in SAT check mode (forward checking).
• -U — only allow RUP additions.

---

🌈 and input and proof are specified as follows 🌈

• INPUT — input file in DIMACS format 📥
• PROOF — proof file in DRAT format (stdin if no argument). so if you don't hand it a proof file, it just reads from stdin like "fine, I'll take what you give me" 🍓

heads up bestie: -D literally deletes the proof file after parsing, and -W bails out at the first warning — those two are not playing around, okay? read twice, run once. 🙈
